Time for a cam

[67 B-body]

Just a thought,,,, Have you considered using oil restrictors to prevent low end starvation and still maintain steady oil flow to the top end?
I used the grooved main bearing and restrictor setup in my 440....

No.

One of the main reasons I picked Chrysler BB motors, over others, is I like the design. That includes the oiling system, except the one point at #4 cam journal. Yeah, I know I sound like a broken record. Just my warped way of thinking. Metal to metal parts, crank, cam, pistons, and those stamped rocker arms, are all meant to never touch each other. Pressurized oil flow is the name of the game, giving a film of oil to rub on, not themselves.
Each of the Chrysler motors I've built, have done the same way, full oiling at #4 cam journal...never any problems, oil pressure or otherwise. A good pump, good relief valve spring...done deal, using the stock oiling system.

Well,,, although I do agree with oil being the film in which two metal parts ride on to prevent touching,,,, the top end doesn't use oil pressure to do this..... The gaps between the rockers and shaft alone are so much that they would never hold or maintain any kind of pressure....
A steady supply of oil is the same thinking as mine,,,, however I don't prefer to do this at the risk of starvation to lower end components... That's why I used restrictors...
I believe it's a balance of supply and demand to perform the function of top end lubrication under higher performance levels,,,, but not disregarding the effects on other components as a result of redirection of the engines life blood...
Peace out.....

Right on, 67 B-body.

Learned long time ago, everybody has their own ideas of what works, or does what it's supposed to do. If you believe in using restrictors, that's exactly what you should do!
This engine building bit is simply a matter of picking the parts and pieces you want to use, and how you put 'em in. Never really thought anything done would be 'wrong', but just getting those parts and pieces to do what you want them to do.

If you are trying to go racing and someone's faster than you....you're doing it wrong.lol

Sometimes there's more than one way to do it and other times it's just really stupid to be doing it any different than the one way. you can get the same result, but in the same amount of time?

Is the effect the same or greater?

all factors that sweep away blanket statements.

Blanket statements?

Otherwise, yeah, your right.
Anything can be done to anything. So-called modifications.
